- - - - continental plates: generally made of granite (less dense)
      - oceanic plates: basalt (more dense)
- - - - A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water

- - - - Prevailing Westerlies
        
        Some of the cool, sinking air continues to move toward the North and South. These winds are called the westerlies and are located between 40°to 60° latitude in both hemispheres.
      - Polar Easterlies
        
        In both hemispheres, the westerlies start rising and cooling between 50° and 60° latitude as they approach the poles. They meet extremely cold air flowing toward the equator from the poles and form the polar easterlies.
      - Trade winds
        
        About 30° north and south of the equator, the warm, moist air that rose vertically cools and begins to sink. Here the sky is clear. There are few clouds and little rainfall. Winds are calm. These are called the horse latitudes, because when food ran out, sailors had to throw horses overboard. Deserts, such as the Sahara in Africa, are also common at 30°N and 30°S. At the horse latitudes some of the sinking air travels back toward the equator. The air moving back toward the equator forms warm, steady winds, known as the trade winds.
- - - - weathering, along with the biosphere (life), atmosphere, and hydrosphere (water), help to form soil
        
        soil can be classified by particle size (sand, silt, clay). Particle size also contributes to porosity, which dictates how well a soil holds nutrients etc
        
        soil can also be classified using soil horizons
        
        (A) Topsoil (rich in organic matter)
        
        (B) Subsoil
        
        (O) Humus on the surface
        
        (C) Parent Material / weathered bedrock
        
        (R) bedrock
        
        *soil horizons are created as bedrock is weathered over time
        
        soil can also be damaged/ destroyed by processes like salinization, erosion, and compaction
        
        types of soil can dictate soil chemistry, which is very important to how supportive the soil is of life. Chemically, various soils have differing CECs (or Cation Exchange capacities), which goes back to how well they can transfer important nutrients into the roots of plants
